SILICONE QUATERNIUM-29.

Insufficient Data / HAIR CONDITIONING

Silicone Quaternium-29 is a synthetic polymer primarily recognized for its hair conditioning properties. It is designed to enhance hair's texture and appearance, with general silicones also offering mild benefits for skin feel and product spreadability.

Hair Conditioning

Science

On hair, Silicone Quaternium-29 operates by smoothing the cuticle, which effectively minimizes frizz and imparts a noticeable shine, resulting in hair that feels softer and more manageable. Similar to related silicones, it can create flexible films, contributing to conditioning benefits in both rinse-off and styling formulations. While its direct mechanism on skin is not extensively documented, silicones typically improve product application and provide a subtle conditioning effect to the skin.
